The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by the person skilled in the art that the described embodiments of the invention can be combined with other embodiments.

In the prior art, the NVMe solid state disk can only be inserted into a motherboard of a computer for use, and is complex to operate, and the use scene of the NVMe solid state disk is single, so that the embodiment of the invention provides the storage device and the data processing system, the storage device can be controlled by the first type of equipment or the second type of equipment, the operation is simple, and the application scene of the NVMe solid state disk can be effectively expanded.

Referring to fig. 1, fig. 1 is a schematic structural diagram of a data processing system according to an embodiment of the present invention; the data processing system comprises a storage apparatus 100, a first type device 105 or a second type device 106, wherein the storage apparatus 100 comprises a housing (not shown), an NVMe solid state disk 101 disposed in the housing, a processing unit 102, a first type interface 103 for connecting with the first type device 105, and a second type interface 104 for connecting with the second type device 106, a PCIe signal line interface of the NVMe solid state disk 101 is connected with the processing unit 102, the processing unit 102 is respectively connected with the first type interface 103 and the second type interface 104, an output end of the first type interface 103 or an output end of the second type interface 104 is respectively connected with a detection input end of the processing unit 102 (not shown), so that the processing unit 102 obtains a first connection state of the first type interface 103 and the first type device 105, and a second connection state of the second type interface 104 and the second type device 106, the processing unit 102 is configured to connect the NVMe solid state disk 101 and the first type interface 103 or the second type interface 104 in a time-sharing manner according to the first connection state or the second connection state.

Under the condition that a PCIe interface of a mainboard is not inserted, data in the NVMe solid state disk can be directly and conveniently accessed.

In particular, through holes corresponding to the first type interface 103 and the second type interface 104 are formed on the shell, so that the plugging and unplugging of the interfaces are realized. The PCIe signal line interface of the NVMe solid state disk is an interface of the high-speed serial computer expansion bus standard, such as an NVMe m.2 interface.

When the first connection state is selected to perform time-sharing connection control of the first type interface 103 and the second type interface 104, the processing unit 102 fixedly connects the second type interface, and when the processing unit 102 detects that the first connection state of the first type interface 103 is the connection state, that is, the first type device 105 is connected to the first type interface 103, the processing unit 102 switches to connect the NVMe solid state disk 101 and the first type interface 103. On the contrary, if the second connection state is selected to perform the time-sharing connection control, the processing unit 102 fixedly connects the first type interface 103, and when the processing unit 102 detects that the second connection state of the second type interface 104 is the connection state, that is, the second type device 106 accesses the second type interface 104, at this time, the processing unit 102 switches to connect the NVMe solid state disk 101 and the second type interface 104.

In the storage device 100 in the embodiment of the present invention, the processing unit is used to acquire the first connection state between the first type interface and the first type device, or the second connection state between the second type interface and the second type device, wherein the processing unit may connect the NVMe solid state disk and the first type interface or the second type interface in a time-sharing manner according to the first connection state or the second connection state, so that the storage device may perform data transmission with the first type device or the second type device in a time-sharing manner, application scenarios of the NVMe solid state disk 101 are enriched, and the practicability of the storage device is effectively improved. In addition, because the data processing system in the embodiment of the present invention includes the storage device, the first type device or the second type device may acquire data stored in the storage device or write new data into the storage device, the system structure is simple, and the practicability is strong.

In a possible embodiment, referring to fig. 2, fig. 2 is a schematic diagram illustrating a detailed structure of a data processing system according to an embodiment of the present invention. The first type device is an upper computer, the upper computer includes any one of a computer, an SoC system, a mobile terminal and a virtual terminal, and the computer includes a desktop computer 204 or a notebook computer. And the first TYPE of interface is a USB interface 203 (such as TYPE-C USB interface, etc.). The second type of device is a device with a PCIe interface, such as a video camera, etc. The second type of interface is a PCIe interface 205, such as an SFF interface or the like.

Therefore, the storage device can be directly and conveniently plugged into a computer through a universal data line (for example, cables with TYPE-C USB interfaces at two ends), and the computer can quickly access and read data in the NVMe solid state disk without a card reader. The PCIe interface is used for being connected with equipment with PCIe interfaces, such as a camera or a video camera and the like, so that the PCIe interface is strong in robustness and resistant to plugging; and moreover, the audio and video data of the camera or the video camera can be recorded and stored in the NVMe solid state disk.

In one possible embodiment, referring to fig. 2, the processing unit includes a controller 200, a multiplexer 201, and a PCIe-to-USB module 202, a PCIe signal line interface of the NVMe solid state disk 101 is connected to an input end of the multiplexer 201, a first output end of the multiplexer 201 is connected to the PCIe-to-USB module 202, the PCIe-to-USB module 202 is connected to the USB interface 203, a second output end of the multiplexer 201 is connected to the PCIe interface 205, an output end of the USB interface 203 or an output end of the PCIe interface 205 is connected to an input end of the controller 200, respectively, and an output end of the controller 200 is connected to a control end of the multiplexer 201.

Specifically, the PCIe-to-USB module 202 is a PCIe-to-USB chip and is responsible for exchanging a PCIe protocol and a USB protocol. The controller 200 may be a single chip, and the multiplexer 201 may be a MUX chip. In practice, taking the USB interface as an example, the status indication signal of the USB interface 203 is output to a DET (detection input) pin on the single chip, and a pin GPIO (general purpose input output pin) of the single chip is connected to the multiplexer 201.

When the output end of the USB interface 203 is connected to the input end of the controller 200, and when the USB interface 203 is connected to the desktop computer 204 through the data line, the USB interface 203 sends a status indication signal to the DET pin of the single chip, the single chip performs logic judgment, and controls gating of the multiplexer 201 through the GPIO pin, so that the multiplexer is selectively connected to the NVMe solid state disk 101 and the PCIe-to-USB module 202, and thus the desktop computer 204 can access data on the NVMe solid state disk 101 through the USB interface.

Similarly, when the output end of the PCIe interface 205 is connected to the input end of the controller 200, and when the PCIe interface 205 is connected to the camera, the PCIe interface 205 gives a status indication signal to the single chip microcomputer, so that the single chip microcomputer controls the multiplexer 201 to connect the NVMe solid state disk 101 and the PCIe interface 205, so that the camera can store the recorded audio and video in the NVMe solid state disk 101.

In one possible embodiment, the storage device further comprises a status indicator light, and the output of the processing unit is connected to the input of the status indicator light to control the operation of the status indicator light after the device is powered on. The status indicator lamp is an LED lamp, and after the storage device is powered on, the processing unit controls the status indicator lamp to emit light so that the indicating device is in a working state. Further, when the storage device utilizes the first type interface and the first connection state of the first type device for time-sharing connection control, the LED lamp is arranged at the corresponding position of the second type interface, so that a user can quickly know that the second type interface is in an available state. The switching indicator lamp can also be an LED lamp, the switching indicator lamp is arranged at a corresponding position of the first type interface, when the first type interface is detected to be connected with the first type equipment, the processing unit extinguishes the status indicator lamp and controls the switching indicator lamp to emit light so as to indicate that the first type interface is in an available state. On the contrary, when the storage apparatus is time-division-on-control using the second type interface and the second connection state of the second type device, the state indicator lamp is disposed at the corresponding position of the first type interface, and the switching indicator lamp is disposed at the corresponding position of the second type interface.

In one possible embodiment, the housing is an antistatic housing. In the using process, the anti-static shell isolates the NVMe solid state disk from external objects, so that the NVMe solid state disk in the storage device cannot be damaged due to contact of hands or static electricity of other objects, and the service life of the storage device is effectively prolonged.

In one possible embodiment, the storage device further includes a heat dissipation unit, and in particular, the heat dissipation unit may be implemented by using at least one of a heat dissipation hole, a heat dissipation fin, a heat dissipation fan, and the like. Referring to fig. 3a and 3b, fig. 3a and 3b are schematic structural diagrams of a storage device according to an embodiment of the present invention, where the housing 301 has heat dissipation holes to dissipate heat in the housing 301 through the heat dissipation holes, so as to prevent the storage device from being broken or damaged due to an over-high temperature, and further prolong the service life of the storage device. When the heat dissipation is realized by using the heat dissipation fins, the heat dissipation fins can be attached to the inner side of the shell or the outer side of the processing unit so as to absorb the heat in the shell or the heat generated by the processing unit. The heat dissipation fan can be matched with the heat dissipation holes for use, and the air outlet can be opposite to the heat dissipation holes, so that the heat dissipation fan can quickly discharge heat through the heat dissipation holes. In addition, the housing 301 has a first type interface 302 and a second type interface 303 thereon.

The above disclosure is only for the purpose of illustrating the preferred embodiments of the present invention, and it is therefore to be understood that the invention is not limited by the scope of the appended claims.
